Hi people!

While discussing about another issue in irc, the possibility of getting
rid of the `def' prefix was raised.

Right now, we have the following language constructs that define things:

 defvar foo = ...;
 defun foo = ...;
 deftype foo = ...;
 defunit foo = ...;

And I plan to introduce yet another one, for sets (like enums and

 defset foo = ...;

Originally, I adopted `defun' from lisp, and just followed the same
trend for the other constructions in order to keep coeherence.  However,
now I am wondering if it wouldn't be better to shorten these names to:

 var foo = ...;
 fun foo = ...;
 type foo = ...;
 unit foo = ...;
 set foo = ...;

I can see a couple of advantages:

a1) It would shorten the size of programs, and also make them easier to

a2) Since Poke is used interactively, having shorter names is a plus.

And one little disadvantage:

d1) The identifiers `var', `fun', `type', `unit' and `set' would all
    become keywords in the language, and some of them are natural names
    for variables.

At this point I feel that the advantages of changing the keywords
overweight the disadvantages, but I would like to hear what you people

As with other important modifications to the language, this is the time
to adopt them, before we release :)
